The one reason I liked RG3 coming out of college, had nothing to do with his legs, it had to do with his accuracy. No matter how athletically gifted you are, you can’t succeed in the NFL, if you don’t have a good feel in the pocket and you aren’t accurate with your passes.
There is a lot of talk about the read option, but what people are forgetting, are the quarterbacks that are running the read option are excellent passers, that is what makes them so dangerous.
RG3, Russell Wilson, Kaepernick, Cam Newton and others have shown the ability to be quarterbacks, that have the ability to run, not just running quarterbacks.
So, when RG3 says he can be better than he was last year, I believe him, because of the experience he gained as a quarterback, not because he can also run.
